Synthesis of Coatings Based on Graphene-Like Materials and Study of Their Physicochemical Properties

Dispersions of graphene oxide and its reduced form have been obtained and characterized by UV spectroscopy. Features of reduction of graphene oxide in the composition of coatings deposited onto solid substrates (aluminum, optical glass, and KDP single crystal) by interaction with different reducing agents (hydrazine hydrate, formalin, ascorbic and citric acids, and ammonium citrate) have been studied. Surface structures have been examined by Raman spectroscopy. The surface morphology of the coatings and defectiveness of the graphene-like materials obtained by reduction of the graphene oxide dispersions on the substrate surface have been investigated.
